To all whom it may concern:

Be it known that I, EoEa'roN Ryerson CASE, a subject of the King of Great Britain, of the city of Toronto, county of York, Province of Ontario, Canada, have invented a certain new and useful Electric Device for Treating Air, of which the following is a specification.

My invention relates to an electric device for treating air, and the principal objects of the invention are to humidify the air in a room, or to treat those suffering from cough or bronchitis, or other bronchia affections, as well as those suffering from throat and lung affections that can be treated in this manner; to supply an in' sectcide to air in a conservatory containing plants, and to supply a fumigating or de odorizing` agent to the air in a room 1n order to purify the same. Another object of the invention is to expedite the dissemination of the treatin agent through the room, and in the following sv ecifcation several apparatus within my invention will be hereinafter particularly described as exemplary means whereby the ob'ects thereof may be carried out, andwhat claim as new will be set forth in the claims forming part of this specification.

Figures 1, 2 and 3 are vertical central lon tudinal sections through apparatus wit in my invention showing different embodiments thereof adapted for distributing a. liquid and a non-liquid treating agent. Figs. 4 and 5 are vertical vcross sections on the lines 4 4, and 5-5, respectively, Fig. 2. Fig. 6 is a vertical central longitudinal section through a modified form of holder for a treating agent, and Fig. 7 is a vertical section on the line 7 7, Fig. 1.

Although in Fig. 1, I show a refieetor as associated with one form of my device, it must be clearly understood that I do not confine myself to using a reector and when a reflector is used, I do not confine myself to using an apertured reflector, such as is shown in Fig. 1.

The particular form of treating-agent holding-means and the constructions and designs whereby suitable electric connections are had. and the particular construction illustrated for controlling or containing the supply of the treating agent, are no t essential to the invention.

` base or member d Since the uantity of treating agent designed to be eld by my device at any one time is relatively quite small, and is preferably located in intimate proximity to the source of heat, it naturally follows that very little time ela ses before the treating agent 1s transforme into the desired state.

The treating agent holding- Ior containingmeans, which also performs the function of a base or support for the resistor in the exemplary disclosures made, may be of metal or of any suitable material well-known inthe 'electrical art, such as porcelain, or fused silica.

G is the base or member supporting the resistor H. i

Preferably intetgrally formed with said is a flange D provided with a breast E projecting beyond one side thereof to form an annular flange so as to support any suitable screen or guard F,

which surrounds the base or member C supporting the resistor. G is a plate faced u against the outer face of the flange D anr suitably secured thereto by any suitable fastenin means such as nuts and bolts commonly esignated I. The plate G is providedwith an opening J therethrough, and projecting through said opening J is a tubular member 2 preferably integrally carried by the Iiange D. 3 is a metal tubular lining for the base or member C, and the tubular member 2, and is designed to contain a nonliquid treating agent 4, which may be of any desired substance such as sulfur, formaldehyde, or spent oxid of iron. Binding posts and nuts, commonly designated 5 may be carried by the late G to which the ends 6 of the resistor are connected. The ends 6 pass through suitable holes 7 shown by dotted lines in Fig. 1 formed in the breast E and flange D, and also in the plate G. A

certain sect1 n of the resistor H is embedded in the longitudinal groove 8 formed in one side of the base or member, and the said groove is afterward closed by any suitable material well-known in the art.

moval of said cap, a suitable lining 11 is interposed between said cap and said flange 1.0.

The said cap closes the open end of the said base or member C as well as the tubular lining 3.

The base or member (l, and the tubular lining 3 are provided respectively with apertures or holes o and 3' through which escapes the treating agent.

If it is desirous of passing air into the tubular lining 3, this may be done in various ways. Forexample. ports 12 and 13 may be formed in the lining 3 and b ase or member (l respectively near their mtake ends. 11 is a valve or damper mounted to be moved on the flange 10 and between the annular shoulder 15 and the lining 11. This damper is provided with a port 16, which when alined with the ports 12 and 13 permits the passage of air into and through the tubular lining 3.

If desired, the form of device illustrated in Fig. 1 may be provided with any suitable reflector 17 suitably carried by the flange D in any manner well known in the art. For example the reflector 17 may be provided with a flange 18 to fit around the flange D, and the flange 18 may be clamped in place by a split ring 19 havlng fastening means in the form of ears and a coupling pin commonly designated 20. Formed in the said reflector, if desired, are a plurality of apertures or openings 21 so as to permit currents of air to pass through said reflector and so facilitate the dissemination of the treating agent throughout the room. Since the temperature will be higher on the inner side of the reflector than on the outer side, it follows that currents of air will flow through the apertures or openings 21 into and out of said reflector.

It is well-known in the art that reflectors of different shapes are used to reflect heat waves or rays electrically generated, and these reflected heat waves or rays cause air currents in a room, which also will disseminate the treating agent.

If desired, any suitable pivoting means commonly designated 22, and preferably carried by the plate G may be used to pivot the form of device illustrated in Fig. 1 to a suitable stand or support 23.

The metal lining 3 may be readily removed from the base or member C for cleaning purposes.

n Fig. 2. I show substantially the same form of device as is illustrated in Fig. 1, except that the base or member C doesnot possess a tubular lining. The resistor H is coupled to any suitable binding posts 5 and is otherwise suitably associated with said base or member C. The control of air into and through the base or member C is controlled by forming a port a in the cap 9', the

port being normally closed by the lining 11.

3y loosening the cap 9', the port a may be fully opened to allow passage of air into and through the base or `member C. 4 is the treating agent mounted within the base or member C', and this can be replenished by removing the cap 9 as will be understood.

In Figs. 2 and 3, I show that my device may be employed without the use of a, reflector.

The form of disclosure in Fig. 3 shows my device adapted for sup l inl a liquid treating agent to the air. Ef 1e use or member fl preferably integrally forms part of the flange D', though not essentially, and the 80 resistor is carried by the said parts, and suitable electrical connections are had in an suitable manner, as will be understoo Preferably integrally formed with the flange D' is a tubular member 2 which communi- 85 cates with the interior of the base or member C". 11l is a metal lining suitabl secured within the tubular member 2 and' coupled thereto is the valve easing 24.' This valve casing is provided with an inlet 25 whereby 90 fluid is conducted by any suitable means (not shown) from a suitable source of supply (not shown). The valve 26, of a Well-known form, controls the supply of fluid through the duct 27 into the base or member C".

The fluid transformed b the heat escapes from the base or member L by the aperture or opening 28 preferably located in the position shown in Fig. 3, so that the base or member C" may contain quite a sup ly of fluid in the initial stage without the oss of the fluid through the said aperture or opening 28. So soon as the various parts described become fully heated, the fluid escaping from the valve casing 24 will begin to be 105 vaporized.

In the form of base or holder C" illustrated in Fig. 6, an open trough 29 is rovided to receive the treating agent. is form of base or member shows clearly that it is not absolutely necessary to pass the treating agent through the base or member of the device.

While I have described what I consider to be the best embodiments of my invention, I desire it to be understood that the principle may be embodied in many different forms, and I desire not to be limited beyond the requirements of the terms of my claims and the prior art.
